The Sikora buffer method was designed to reproduce the same soil-buffer pH obtained with the SMP buffer method. Therefore, the Sikora buffer method is suited for the same type of soils intended for the SMP buffer method which includes silt loam that can contain appreciable extractable Al.
A buffer is an aqueous solution that has a highly stable pH. If you add acid or base to a buffered solution, its pH will not change significantly. Similarly, adding water to a buffer or allowing water to evaporate will not change the pH of a buffer.
